notification.plugin_zip_malloc

Error message

notification.plugin_zip_malloc

What it means

The match maps ZipArchive::ER_MEMORY to 'Zip: Malloc failure'. libzip could not allocate the memory it needs to index the archive while opening it. This is not about the zip being bad - it is the PHP process hitting its memory ceiling (memory_limit) or a container cgroup memory cap during open().

Solutions

1. Check the web SAPI's actual limit: php -r via a phpinfo page or ini_get('memory_limit') rendered from a route - raise it (e.g. 512M) for the install.
2. Raise the container/pod memory limit if the process is being OOM-capped.
3. Retry the install when the server is less loaded (other requests consume the same limit).
4. If a custom build has no zlib support, verify the zip extension is fully functional: php -m | grep zip.

$limit = ini_get('memory_limit');
if ($limit !== '-1' && parseByteSize($limit) < 256 * 1024 * 1024) {
    ini_set('memory_limit', '512M'); // raise for the duration of the plugin install
}

When it happens

Trigger: installMarketplacePlugin() opening a large plugin zip under a low memory_limit (shared hosting defaults of 64-128M are common victims), or a container whose memory cgroup limit is near exhaustion; memory pressure from other concurrent requests finishing the budget.

Common situations: Shared hosting with low memory_limit installing asset-heavy plugins; Kubernetes pod memory limits; php.ini memory_limit left at a small value for the web SAPI while CLI has a higher one.
